When the vehicle equipped with the vehicular decorative component 1 of the present embodiment travels at night, one of the two light source units 2A and 2B is turned on.

  FIG. 5 is a diagram illustrating a state in which the first light emitting pattern LP1 is caused to emit light by the first pattern forming unit 14. When the first light emission pattern LP1 is caused to emit light, the first light source unit 2A of the first pattern formation unit 14 is turned on while the second light source unit 2B of the second pattern formation unit 15 is turned off. The light L1 emitted from the first light source unit 2A is taken into the light guide member 4 and guided through the light guide member 4.

  The light L1 guided in the light guide member 4 is reflected by the respective reflecting surfaces 17a (FIG. 3C) of the plurality of first prism cut portions 17 constituting the first light emitting portion 12 in the first pattern forming portion 14. The first outgoing pattern light L11 is emitted from the outer surface 4a. In this way, by turning on the first light source unit 2A, the first emission pattern light L11 is generated in the first light emission unit 12, and the lattice-shaped first emission pattern LP1 shown in FIG. 5 emits light.

  FIG. 6 is a diagram illustrating a state in which the second light emitting pattern LP2 is caused to emit light by the second pattern forming unit 15. When the second light emitting pattern LP2 is caused to emit light, the second light source unit 2B of the second pattern forming unit 15 is turned on in a state where the first light source unit 2A of the second pattern forming unit 15 is turned off. The light L <b> 2 emitted from the second light source unit 2 </ b> B is taken into the light guide member 4 and is guided through the light guide member 4.

  The light L2 that is guided through the light guide member 4 is reflected by the reflection surfaces 18a (FIG. 4B) of the plurality of second prism cut portions 18 constituting the second light emitting portion 13 in the second pattern forming portion 15. It is emitted as the second emission pattern light L22 from the outer surface 4a. As described above, the second light emission unit 13 generates the second emission pattern light L22 by turning on the second light source unit 2B, and the lightning-like second light emission pattern LP2 illustrated in FIG. 6 emits light.

As described above, the light source unit 2A (2B) corresponding to the light emission pattern LP1 (LP2) to be emitted is selected from the two pattern forming units 14 and 15 provided on the light guide member 4 to be turned on. Only the light emitting part 12 (13) corresponding to the light source part 2A (2B) emits light, and the light emitting part 13 (12) corresponding to the light source part 2B (2A) that is not lit does not emit light. For this reason, it is possible to cause the specific light emitting portions 12 and 13 to emit light only by switching the light source portions 2A and 2B to be turned on and changing the light incident direction with respect to the light guide member 4, and the desired light emission patterns LP1 and LP2 Can be generated.

  In this way, if the pattern forming portions 14 and 15 are provided for each of the light emission patterns LP1 and LP2, the light source portions 2A and 2B to be emitted are selected and the light incident direction of the light incident on the light guide member 4 is changed. A plurality of light emitting patterns LP1 and LP2 can be made to emit light individually while being one light guide member 4. Therefore, it is possible to generate a good-looking light emission pattern by generating various emission pattern lights with one light guide member 4.

(Third embodiment)
Next, a vehicle decorative component 30 according to a third embodiment of the present invention will be described.
The basic configuration of the present embodiment is substantially the same as that of the second embodiment described above, but the pattern shapes of the light emitting portions 33A to 33F are different.

FIG. 8 is a plan view showing a main configuration of the vehicle decorative component 30 according to the third embodiment.
As shown in FIG. 8, the decorative component 30 for a vehicle according to the present embodiment has seven pattern forming portions 35A to 35F. On the inner surface 34b of the light guide member 34 having a hexagonal shape in plan view, six light emitting portions 33A to 33F having the same pattern shape are formed. For example, the light emitting portions 33A to 33F in the present embodiment have a pattern shape representing an “arrow” in a plan view of the light guide member 34, and are formed in a line, and all indicate the same direction. .

  In the present embodiment, the light source patterns 2A to 2F corresponding to the light emitting units 33A to 33F arranged in a row are sequentially turned on or off, so that the light emission patterns LP indicated by the arrows sequentially emit light in the light emitting units 33A to 33F. Thus, when viewed from the outer surface 34a side of the light guide member 34, the arrow appears to move in one direction.

  In this way, by arranging a plurality of light emitting portions 33A to 33F having the same pattern shape on one light guide member 34 while shifting the positions of the light emitting portions 33A to 33F, and sequentially lighting the light source portions 2A to 2F, Movement can be given to the display as a whole. The light emission pattern LP is not limited to an arrow, and an animation can be displayed by using another shape.

  In the vehicle decorative component according to the first to third embodiments described above, various patterns can be considered as a pattern to emit light (display) with the light guide member.

  For example, by displaying characters as light emitting patterns with a light guide member, the vehicle can be used as a communication tool for oncoming vehicles and pedestrians when the vehicle is stopped. For example, by displaying “in boarding / exiting” on the light guide member, it is possible to convey to the surroundings that a person is getting in or out of the vehicle.

  In addition, when the pedestrian crosses the road, the vehicle recognizes the pedestrian, and the vehicle decorative component (light guide member) provided on both or one of the front side and the rear side of the vehicle, for example, By displaying “Pedestrian crossing”, the reason for stopping can be communicated to the surroundings.

  Moreover, when it is lined up on the road to enter the parking lot, for example, by displaying “Waiting for parking” on the light guide member, it can inform the surroundings that it is lined up for parking.

  In this way, by displaying the above-described character informing the vehicle status on the decorative component (light guide member) for the vehicle, it is possible to call attention to the following vehicle or bicycle. The contents of characters to be displayed can be set as appropriate, and can be used in place of hazard or headlight passing.

Moreover, it is good also as a structure which made the decorative component for vehicles and the communication tool compatible in connection with a connected car, an advanced driving assistance system (ADAS), etc.
For example, when a vehicle is stolen, it may be notified to the surroundings by displaying “theft car” on the light guide member in conjunction with GPS or a network.

  In addition, when an ambulance is called in the car or when rescue is required, characters such as “HELP” are displayed on the light guide member in conjunction with the GPS or network, so that pedestrians and oncoming vehicles around Tell the car that they need visual help.

As shown in FIG. 9, the vehicle decorative component 40 of the present embodiment includes a light guide member 44 having a rectangular shape in plan view, seven light source parts 2A to 2G, the above-described housing (not shown), and outer lens (not shown). And can display decimal Arabic numerals composed of seven segments (pattern forming portions 45A to 45G).

  The light source units 2 </ b> A to 2 </ b> G are provided to face each of the four sides 44 a to 44 d of the light guide member 44. Two light source parts 2A and 2B are provided on one long side 44a side of the light guide member 44, and two light source parts 2C and 2D are provided on the other long side 44e side. In addition, one light source 2E is provided on one short side 44c side of the light guide member 44, and one 2F is provided on the other short side 44d side. In addition, one light source unit 2G is provided at one corner (for example, the corner portion 44j) of the light guide member 44. In addition, arrangement | positioning of each light source part 2A-2G with respect to the light guide member 44 can be changed suitably.

  On the inner surface 44 b of the light guide member 44, seven light emitting portions 43 </ b> A to 43 </ b> G constituting Arabic numerals in the plan view of the light guide member 44 are formed. Each of the light emitting portions 43A to 43G has a predetermined pattern shape constituted by a plurality of prism cut portions (not shown). In the present embodiment, in a state where the light guide member 44 is viewed in plan, the pattern shapes of the light emitting portions 43A to 43G are substantially the same. For this reason, all of the emitted light pattern lights emitted from the light emitting parts 43A to 43G of all the pattern forming parts 45A to 45G have the same shape, and each of them represents a part of a number.

  As shown in FIG. 9, in the present embodiment, seven light source units 2A to 2G and seven light emitting units 33A to 33G correspond to each other in a one-to-one relationship, and seven pattern forming units 45A to 45G are configured. Specifically, the first pattern forming unit 45A is configured by the first light source unit 2A and the first light emitting unit 43A. The first light source unit 2B and the second light emitting unit 43B constitute a second pattern forming unit 45B. The third pattern forming unit 45C is configured by the third light source unit 2C and the third light emitting unit 43C. The fourth pattern forming unit 45D is configured by the fourth light source unit 2D and the fourth light emitting unit 43D. The fifth light source unit 2E and the fifth light emitting unit 43E constitute a fifth pattern forming unit 45E. The sixth pattern forming unit 45F is configured by the sixth light source unit 2F and the sixth light emitting unit 43F. The seventh pattern forming unit 45G is configured by the seventh light source unit 2G and the seventh light emitting unit 43G.

For example, as long as at least two of the emitted pattern lights emitted from the light emitting units 43A to 43G have the same shape, the shapes of the other emitted light pattern lights may be different from each other.

(Fifth embodiment)
Next, a vehicle decorative component 50 according to a fifth embodiment of the invention will be described.
FIG. 10 is a perspective view showing a main configuration of a vehicle decorative component 50 according to the fifth embodiment. FIG. 11 is a plan view showing a main part configuration of a vehicle decorative component 50 according to the fifth embodiment.

  As shown in FIGS. 10 and 11, the vehicle decorative component 50 of the present embodiment includes a light guide member 54, two light source parts 2 </ b> A and 2 </ b> B, and a frame-shaped shaped article 52.

  The light source parts 2A and 2B are provided on two adjacent sides 54c and 54d of the light guide member 54, respectively.

  The shaped article 52 is disposed on the light emitting side of the light guide member 54, for example, on the outer surface 54 a of the light guide member 54. In addition, you may arrange | position the molded article 52 on the outer lens 7 shown in FIG.

  On the inner surface 54b of the light guide member 54, first light emitting portions 53Aa and 53Ab and second light emitting portions 53Ba and 53Bb are formed at positions adjacent to the modeled object 52 in a state where the light guide member 54 is viewed in plan view. Has been. Hereinafter, when the first light emitting portions 53Aa and 53Ab and the second light emitting portions 53Ba and 53Bb are not distinguished, they may be simply referred to as “light emitting portions 53A and 53B”.

  The first light emitting portion 53 </ b> Aa and the second light emitting portion 53 </ b> Ba are formed so as to be located outside the frame of the modeled object 52. On the other hand, the first light emitting portion 53Ab and the second light emitting portion 53Bb are formed so as to be positioned within the frame of the molded article 52.

  In the present embodiment, as shown in FIG. 11, the first light emitting portions 53Aa and 53Ab and the first light source portions 2A corresponding thereto constitute a first pattern forming portion 55A. Further, the second light emitting portions 53Ba and 53Bb and the corresponding second light source portions 2B constitute a second pattern forming portion 55B.

  The light emitting portions 53A and 53B have a predetermined pattern shape composed of a plurality of prism cut portions 53a and 53b, respectively. In the present embodiment, the first light emitting portions 53Aa and 53Ab and the second light emitting portions 53Ba and 53Bb have elongated pattern shapes that are adjacent to the corresponding sides of the four sides of the shaped article 52, respectively.

  In the present embodiment, the first light emitting portion 53 </ b> A and the second light emitting portion 53 </ b> B partially overlap each other on the inner surface 54 b of the light guide member 54. That is, the inner surface 54b of the light guide member 54 includes the first region KB and the second region KC in which the first light emitting unit 53A and the second light emitting unit 53B are mixed inside and outside the frame of the modeled object. In the first region KB and the second region KC, there are a plurality of both the prism cut portions 53a of the first light emitting portion 53A and the prism cut portions 53b of the second light emitting portion 53B.

  Also in this embodiment, the respective reflecting surfaces (not shown) of the plurality of prism cut portions 53a and 53b constituting the respective light emitting portions 53A and 53B are oriented in the respective directions so as to face the corresponding light source portions 2A and 2B. It's all there. For this reason, even if the plurality of prism cut portions 53a and 53b constituting both the light emitting portions 53A and 53B are formed in the same region (first region KB and second region KC), the light emitting portion 53A. The prism cut portion 53a and the prism cut portion 53b of the light emitting portion 53B have different directions of reflection surfaces, so that only the light emitted from a specific direction is selectively selected by the prism cut portions 53a and 53b. Can be reflected.

  With such a configuration, when the first light source unit 2A is turned on, the light emitted from the first light source unit 2A is emitted as emitted pattern light at the light emitting units 53Aa and Ab of the light emitting unit 53A, and the shaped article A light emission pattern LP5A (hereinafter sometimes simply referred to as “shadow”) that gives a shadow-like impression to one side of 52 is generated.

  In addition, when the second light source unit 2B is turned on, the light emitted from the second light source unit 2B is emitted as the emission pattern light at the light emission units 53Ba and Bb of the light emission unit 53B, and the other side of the model 52 A light emission pattern LP5B (hereinafter sometimes simply referred to as “shadow”) that gives an impression like a shadow is generated.

  Thus, the direction in which the shadow of the shaped object 52 is generated can be changed by switching the light source units 2A and 2B to be turned on.

  When the first light source unit 2A and the second light source unit 2B are turned on at the same time, the emission pattern light is emitted simultaneously from both the light emission units 53A and 53B. At this time, in the first region KB and the second region KC, both the emission pattern light from the light emission part 53A and the emission pattern light from the light emission part 53B are emitted. Therefore, the brightness of the pattern light emitted from the first area KB and the second area KC becomes brighter than the brightness of the light emission patterns emitted from the other light emitting areas of the light emitting portions 53A and 53B. It is possible to generate a light emitting pattern that looks good in which the brightness of the emitted pattern light is partially bright. This may be a kind of design.

  In the present embodiment, the configuration in which the prism cut portions 53a and 53b of the light emitting portions 53A and 53B are mixed in the first region KB and the second region KC has been described. However, according to the required light emission pattern design. Thus, the prism cut portions 53a and 53b may not be formed in either the first region KB or the second region KC, or the prism cut may be performed in only one of the first region KB and the second region KC. It is good also as a structure in which the part was formed.

  In the present embodiment, the two light source units 2A and 2B (pattern forming units 55A and 55B) are provided so that the shadow can be reproduced from two directions. It is good also as a structure which can reproduce the shadow of.

(Modification)
Next, as a modified example of the fifth embodiment, a configuration that can reproduce a shadow from three directions on a modeled object will be described. FIG. 12 is a plan view showing a configuration of a vehicular decorative part 51 that is a modification of the fifth embodiment.
As in the vehicular decorative part 51 shown in FIG. 12, the third light source part 2 </ b> C may be further provided at a position facing the corner part 54 j of the light guide member 54.

  On the inner surface 54b of the light guide member 54, a third light emitting portion 53Cb is formed in the first region KB in the frame of the modeled object 52 in plan view, and the third light output is output in the second region KC outside the frame of the modeled object 52. A portion 53Cc is formed. The third light emitting portions 53Cb and 53Cc and the corresponding third light source portion 2C constitute a third pattern forming portion 55C.

  The respective reflecting surfaces of the plurality of prism cut portions (cut portions) 53c constituting the third light emitting portions 53Cb and 53Cc are aligned in directions so as to face the third light source portion 2C. Therefore, the light emitted from the third light source unit 2C can be selectively reflected by the plurality of prism cut units 53c.

  In such a configuration, when all of the three light source units 2A to 2C are turned on simultaneously, the shaped object 52 shown in FIG. 12 is formed on the light guide member 54 by the respective emission pattern lights emitted from the light emission units 53A to 53C. It is possible to more naturally reproduce the shadow that can be produced when light is directed toward the modeled object 52 from the diagonally upper side on the corner 52j side.

  In this example, there is no region where the light emitting portions 53A, 53B, and 53C overlap on the inner surface 54b of the light guide member 54. Therefore, even if the light source portions 2A to 2C are turned on at the same time, the light emitting portions 53A, 53B, The brightness of the outgoing pattern light emitted from 53C is substantially equal. Therefore, the light emission pattern has a cleaner appearance.

  In the above-described configuration, only the prism cut portion 53c constituting the third light emitting portion 53C is formed in the first region KB and the second region KC in the light guide member 54, but the present invention is not limited to this. In the first region KB and the second region KC, three types of prism cut portions 53a, 53b, and 53c of the light emitting portions 53A, 53B, and 53C may be formed.

  Or you may provide the light emission part from which the direction of each reflective surface of each prism cut part differs mutually in each of 1st area | region KB and 2nd area | region KC. In this case, a light source unit corresponding to the light emitting unit in the first region KB and a light source unit corresponding to the light emitting unit in the second region KC may be provided, and each light source unit may be driven individually.

  FIG. 13 and FIG. 14 are schematic views showing configurations of other variations in the vehicle decorative component 50 of the fifth embodiment. FIG. 13 is a diagram in which a light emission pattern corresponding to the first shadow S <b> 1 is formed around the modeled object 52. FIG. 14 is a diagram in which a light emission pattern corresponding to the second shadow S <b> 2 is formed around the modeled object 52.

  As shown in FIGS. 13 and 14, a plurality of shaped objects 52 are arranged side by side on the outer surface 54 a of the light guide member 54, and a plurality of shaped objects 52 are adjacent to each other along a side in one direction of each shaped object 52. The light emitting portions 531 are provided, and a plurality of light emitting portions 532 are provided adjacent to each of the positions along the other side of each shaped article 52. The light emitting units 531 and 532 have different light source units. According to this configuration, the positions of the shadows S1 and S2 generated around each shaped article 52 can be changed as shown in FIGS. 13 and 14 by switching the light source unit to be lit.

  The shape of the shaped object 52 is not limited to the illustrated frame shape, and may be other shapes. In addition, the number and arrangement of the shaped objects 52 and the size of each shaped object 52 can be changed as appropriate.

  As described above, according to each embodiment of the present invention, it is possible to generate a light-emitting pattern with good appearance by generating various patterns with one light guide member.

The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, configurations unique to each of the plurality of embodiments can be combined as appropriate.

  In each embodiment described above, the number of light emitting units corresponding to each light source unit is not limited to one, and a configuration in which a plurality of light emitting units correspond to one light source unit may be employed. In addition, a configuration in which a plurality of light source units correspond to one light emitting unit may be employed. For example, since two light source units that emit light of different colors correspond to one light emitting unit, the color of the emission pattern light emitted from the light emitting unit can be changed.

  The present invention can be used for decorative parts for vehicles such as grills, garnishes, and interior decorations.
